SiRFstarIV is out

Jul 28, 2009 gps navigation, misc news 6 Comments

After acquiring SiRF just about a month ago, CSR is continuing their highly popular SiRF series with SiRFstarIV. This is not just plain old GPS receiver though. SiRFstarIV is a location aware architecture with self assistance (SiRFaware), and micro power GPS technology.

Advantages of SiRFstarIV is that it doesn’t drain your batteries, and it doesn’t need network aid to get a satellite fix. CSR claims their new platform can maintain better than hot start condition and therefore be turned off without worrying about startup delays.

SiRFstarIV has twice the search capacity of SiRFstarIII platform with enhanced sensitivity, ability to maintain hot-start condition while only using 50-500 microamperes, ability to support accelerometers and other sensors and DSP technology that searches for jammers and removes them prior to correlation for better GPS performance.

The first product from the new SiRFstarIV platform is called SiRFstarIV GSD4t and it is already out… Read More …

Haicom HI-602DT real time GPS tracking

Dec 29, 2008 gps navigation, tracking 6 Comments

If you’re planning to keep an eye on whereabouts of someone or something that moves you’re going to need a real time GPS tracking system. Today we’re talking about Haicom HI-602DT It contains the usual GPS module, but also the GSM module ( a SIM card slot) to transmit its location back to the base. HI-602DT is slightly different from the others in this respect. When it comes to transmitting its position back to the tracker it does not use text messages – it uses the GSM dial tone transmission solution.

Therefore – they claim – you can use any SIM card you want without any monthly fees, or extra messaging costs; other than the actual calls made by the tracking system. The downside however is that you’re going to have to attach this decoder to your phone; just like seen in this picture to the right.

HI-602DT uses the most unique DTMF technology via GSM voice channel to send back the real time GPS location data directly to another phone. The user can track any moving object live on the map without Internet access and a call center in between (Tracking is free of charge with no need to pay any monthly subscription to a service)…. HI-602 continuously sends back real time location data. This facilitates route tracking on local GPS or Google maps. You can actually watch the vehicle movements live on a map similar to a car navigation system….

…User can insert any local GSM SIM card (or pre-paid SIM card, etc.) making it only necessary to pay a phone call charge when tracking is in use. Also, by setting up three priority call back telephone numbers inside HI-602DT, user can press the SOS button and the tracker will immediately send a SMS with GPS location to the preset numbers.

It is different, but it is a solution for live GPS tracking. It gives you the freedom to use any SIM card you want and leave out the middleman (other than your own cell phone network provider). It can last up to 5 days without a recharge and comes with all sort of accessories to assemble in a vehicle.

Other features that you can enable with a few optional accessories include:

• two way voice communications
• ability to use a panic button to make a call from the tracker side
• ability to disconnect fuel and battery of a vehicle from any phone when installed in a car
• vibration sensor to automatically dial back when the movement occurs

If you’re worried about such tracking devices may we also suggest a GPS jammer ;)

gps tracking jammer

Apr 21, 2008 gps navigation, tracking 1 Comment

Here we have another anti gps tracking device which looks really easy to use. All you have to do is to plug into your car charger and it will jam all the frequencies that are around the 1575.42 MHz range within a 5 meter radius. Of course you can say good bye to using your own GPS navigation system as well when you have this GPS jammer on.

This one is sold in the U.K. for only £149.99.

If you’re looking for something a little more advanced you should check out the GPS and GSM jammer… Read More …

another GPS / GSM jammer: Wave Bubble

Oct 8, 2007 gps navigation, hacks 2 Comments

We had talked about some other commercial and DIY GPS jammers before but here we are presenting another one today. Built by Limor and presented on ladyada.net, this device is a self-tuning portable RF jammer that can can jam many different frequency bands without the need for a spectrum analyzer. Even though the earlier version seen on left has big antennas sticking out, the later version on the right is more compact, small enough to fit inside a pack of cigarettes.

Wave Bubble has an internal lithium-ion battery that can provides up to 2 hours of jamming when using two bands such as cell phones or 4 hours if you only care to scramble a single band, such as cordless phones, GPS devices, WiFi, bluetooth, etc. The battery is rechargeable via a mini-USB connector or 4mm DC jack, however alternatively you can use 3 AAA batteries.

Even the instructions are complete don’t think you can finish this jammer in one weekend for it involves difficult soldering, obscure parts, and other necessary equipment to debug. Also keep in mind the device is not for sale here nor anywhere else for it would be against FCC regulations. Do NOT contact us or Limor for how to purchase please.

GPS jammer against tracking devices

Jul 31, 2007 gps navigation, tracking 38 Comments

This GPS jammer simply plugs into your car charger and jams any signal broadcasting within 1450 to 1600Mhz range. It’s coverage is about 2 to 4 meters which is big enough to interrupt any GPS tracking device that may have been implemented in your vehicle. Pricing is not known yet but check out this site soon for it will be available very soon.

build your own GSM GPS tracking device

Jul 16, 2007 gps navigation, hacks, tracking 36 Comments

If you are into electronics and have some extra cash laying around here is your weekend project. You can build your very own GSM GPS tracking device. The materials will cost you about $280, the most expensive piece being the GM862-GPS module for $183.

If you follow his directions carefully, in the end you should be able to switch the module on and off, send text SMS messages through the module and fetch GPS positions from it which should look something like this:

Request GPS
AT$GPSACP got: AT$GPSACP
GPSACP: 131924.999,5333.9291N,00954.8841E,2.6,34.0,3,29.78,0.32,0.17,130707,07
OK

And if you are paranoid of people who can build one of these things you should get yourself a GPS and GSM jammer…via

GPS and GSM jammer

Jan 29, 2007 gps navigation, hacks, tracking 80 Comments

If the do-it-yourself version of the GPS jammer is above your skills you may be interested in this GPS and GSM jammer. This GPS / GSM jammer plugs into the cigarette lighter in your car and gives your paronoid self a peace of mind. It is manufactured by a company in Netherlands called DetectNu, however it is not showing in their online shop at this moment.

The device is designed to prevent a GPS logger that may be implemented in your car to collect data and send it back to the base station.

Because GSM jammers will only prevent GPS/GSM tracking devices to communicate with the base station. The GPS/GSM devices are still able to receive and buffer all GPS positions. The tracking devices will still be able to send out all the GPS positions if the car or when the GSM jammer is shut down. So they can still see where you went that day.

Only GPS jammers will prevent the GPS loggers and GPS/GSM devices to get GPS positions from the Satellites. But they still can track you by the GSM network used by the GPS/GSM devices or track you by your mobile phone.

We have a no information on pricing or availability.

homemade GPS jammer

Jan 29, 2007 gps navigation, hacks, tracking 10 Comments

Today we are featuring an article from Phrack – an online hacker magazine. What we have is a do-it-yourself GPS jammer that can have a range of upto several hundred feet. Keep in mind this is not an easy hack – a bachelors in electrical engineering seems like a prerequisite.

The GPS band pass filter is a 2-pole Toko 4DFA-1575B-12 ceramic dielectric filter from Digi-Key[4], part number TKS2609CT-ND. This part is optional, but helps clean up the RF spectrum before further amplification. The filter’s insertion loss is around 2 dB.

The final RF amplifier is a WJ Communications AH102. It provides another 13 dB of gain, with a higher P1dB compression point of around +27 dBm (500 mW). The AH102 draws the most current of any part, and is not really necessary if you’re aiming for a low range, low current, battery operated device.

This hack is designed to be a low cost one, only using components you can easily find at a trip to Radio Shack. It targets the Global Positioning System (GPS/NAVSTAR) L1 frequency of 1575.42 MHz. Also keep in mind this device will not work against the Russian GLONASS or European Galileo systems.

General Dynamic gets contract to develop advanced GPS interface and Navigation Tool: GIANT

Apr 6, 2006 gps navigation, misc news Leave a comment

General Dynamic was announced today as the winner of an $8.3 million contract to provide the development of the Global Positioning System Interference And Navigation Tool (GIANT). GIANT is no ordinary GPS system. It can work under environments where GPS jammers are being used since GIANT models the satellites and user equipment, receivers and antennae in real-world scenarios, then provides a comprehensive evaluation of the GPS environment. More information on GIANT can be found here.

General Dynamics Advanced Information Systems, a business unit of General Dynamics Corp. , was awarded an $8.3 million contract to provide development, analysis, operations and support of the Global Positioning System Interference And Navigation Tool (GIANT).

GIANT is a simulation tool and mission-planning aid used to determine navigation system performance and its impact on weapons system effectiveness. For instance, the system can be used to improve precision-guided munitions accuracy in a GPS-jamming environment. GIANT models the satellites and user equipment, receivers and antennae in real-world scenarios, then provides a comprehensive evaluation of the GPS environment. There are currently more than 200 registered GIANT users, spanning the acquisition, test, intelligence and operations communities.

“GIANT prepares the warfighter for real situations through simulated exercises and war gaming. It gives the analyst a more complete GPS information picture,” said Ron Sizemore, Director of the Advanced Technologies and Simulations Business Group for General Dynamics Advanced Information Systems. “We plan to use GIANT in the future as the baseline for operational mission planning for the Air and Space Operations Center weapon system. No other GPS related tool has all these capabilities and this contract reflects General Dynamics’ leading position as a developer of valuable GPS modeling tools for the government.”… via
